Nitrate Removal from Aqueous Solution by Orange Peels as an Adsorbent

M. Vijaya Kumar, H. Prasad Raju.

Abstract
One of the best water treatment technologies around the world has been the adsorption process. In this process activated carbon was considered as universal adsorbent for the removal of diverse types of pollutants from water. Thus, the widespread use of commercial activated carbon became restrictive due to its exorbitant operation and maintenance cost. In the present research work, the authors used activated carbon that has been produced from orange peels by chemical activation technique withZnCl2 as activating agent.The scanning electron microscopy (SEM) images of the activated carbon have shown the higher cavities.By using the energy dispersed X-ray (EDX) analysis, carbon content in the modified orange peels sample was detected. The optimum conditions of sorption were found to beat sorbent dose of 0.3 g in 100 mlwithconcentration 50 mg/L of NO3- solution, contact time =720 minutes and pH = 3. Under the optimum conditions, the removal efficiency was 86.00%.The adsorption mechanisms were investigated with two simplified kinetic models, i.e., first and second-order, and intraparticle diffusion were tested. The correlation coefficient obtained for second order kinetic model is 0.9961 which indicatedits effectiveness in adsorption capacity.

Key words: Nitrate, Groundwater, Orange peels, Activated Carbon, Zinc Chloride, SEM, EDX.
